Dickson police have opened an investigation into the death of a two-month-old child after the medical examiner classified the death as a homicide. Det. James Eubank confirmed that there is an open investigation into the Sept. 24 death of Grayson Micheal Bowker-Huse after an autopsy ruled the cause of death was blunt force trauma to the head. Eubank said that the child’s death was originally believed to be from natural causes until the autopsy results were released. On Thursday, Eubank said he still had not received any official notification from the state medical examiner of the findings, and was unaware of the results until the child’s mother, Brittany Sanders, showed him a copy that she received in January. Eubank said he has since talked with the medical examiner’s office and decided to open an investigation. Eubank said Huse had been in the hospital for four days in September and was released but within hours of leaving the hospital there was a 911 call to the child’s home. While Eubank would not discuss the status of the investigation or whether there are any suspects, he did confirm that the child was in the custody of his biological father at the time of his death. The father, Robert Huse, pleaded guilty in 2008 to accessory to child abuse after the fact following a five-month-old child suffering a head injury. Huse was placed on probation for two years and the child’s mother, who is now divorced from Huse, received three years on probation. That child and a sister were placed in their grandparents’ custody by the Tennessee Department of Children’s Services, but after two years were returned to Huse. Since Grayson Huse’s death has now been ruled a homicide, the two older children have been placed in foster care by DCS.
